Intshayelelo
Heptanal. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-heptanaldehyde:
Umgangatho:
1. Imbonakalo: I-Heptanal ilulwelo olungenambala kunye nevumba elimnandi elikhethekileyo.
2. Uxinzelelo: I-Heptanal inoxinano oluphezulu, malunga ne-0.82 g/cm³.
4. Ukunyibilika: IHeptanal iyanyibilika etywaleni nakwizinyibilikisi ze-ether, kodwa phantse ayinyibiliki emanzini.
Sebenzisa:
1. I-Heptanaldehyde yinto ebalulekileyo ephakathi, engasetyenziselwa ukuveliswa kwe-biodiesel, i-ketones, i-acids kunye nezinye izinto.
2. I-Heptanaldehyde idla ngokusetyenziswa ekwenzeni iziqhumiso zokwenziwa, iintlaka, iiplastiki, njl.
3. I-Heptanaldehyde inokusetyenziswa njenge-reagent yekhemikhali kwaye ingasetyenziselwa kwi-organic synthesis, i-surfactant kunye nezinye iindawo.
Indlela:
Kukho iindlela ezimbini eziphambili zokulungiselela i-heptanaldehyde:
1. I-Heptane oxidation: I-Heptanaldehyde inokulungiswa nge-oxidation reaction phakathi kwe-heptane kunye ne-oksijini kumaqondo aphezulu.
2. I-Etherification ye-vinyl alcohol: I-Heptanal inokufumaneka kwakhona nge-etherification ye-1,6-hexadiene kunye ne-vinyl alcohol.
Ulwazi ngoKhuseleko:
1. I-Heptanaldehyde inephunga elimnandi kwaye inefuthe elicaphukisayo emehlweni kunye nenkqubo yokuphefumula, ngoko kufuneka igcinwe kude namehlo, umlomo kunye neempumlo.
2. I-Heptanaldehyde iyacaphukisa ulusu, ngoko kufuneka ihlanjululwe ngamanzi ngokukhawuleza emva kokudibanisa.
3. Umphunga we-Heptanaldehyde unokubangela intloko, isiyezi kunye nezinye iimpawu ezingathandekiyo, kwaye kufuneka zisetyenziswe kwindawo enomoya.
4. I-Heptanaldehyde iyilwelo oluvuthayo, ngoko ugweme ukudibanisa nomlilo ovulekileyo kunye nokushisa okuphezulu.
